Create symbolic links to workspaces in node_modules directory for better Node.js compatibility

[kensukesaito]

In a Node.js (npm) environment, running npm install with workspaces specified in package.json creates symbolic links to the workspaces in the node_modules directory. However, in Deno, even when nodeModulesDir: auto | manual and workspace are configured in deno.json, or when workspaces are defined in package.json, running deno install does not create symbolic links to the workspaces in the node_modules directory.

This leads to issues where certain npm libraries attempt to reference the workspaces (packages) within the node_modules directory but fail, resulting in errors.
